Rule #3: For More than Two Same-Named Individuals, Use Roman Numeral Suffixes. What if there are more than two same-named individuals in the Johnson family? Then, they can use Roman numeral (i.e. I, II, III, IV, etc.) suffixes after their name, to designate the order in which they were born. Rule #4: âSr.â and âJr.â
Search for: Subunit vaccines are vaccines that use only part of the disease-causing virus. This strategy is used most often when one part of the virus is responsible for creating disease. The part responsible for creating disease is a protein, which we call the antigen. An example of the recombinant subunit vaccine is the hepatitis B virus vaccine.
Recombinant DNA vaccines are based on the expression of biological constructs encoding proteins from specific viral pathogens, and are not themselves made of DNA. Instead, they are made of protein or glycoprotein subunits synthesized in the laboratory using recombinant DNA technology. For example, the HBV vaccine was originally made by extracting and purifying the surface antigen (envelope protein) from serum of individuals exposed to HBV virus.
